"Hollow body filled with foam, and process for the prevention of exit of foam through an aperture of a hollow body to be filled with foam.For the avoidance of leakage of foam through an aperture (26), a wall (25) of a hollow body to be filled with foam, is placed a layer of destructive material (15).Between the opening (26) of the hollow body, and a section of the wall (25), which surrounds it, on the one hand, and a reinforcement piece (27), which has a hole (28), which overlaps with the opening (26).On the other hand, a connection between a section of the wall (25), and the reinforcement piece (27) is produced without heating of the wall and the considerable piece of reinforcement in short distance of the opening.The hollow body is filled with foam and a layer of material destructive (1 5) is removed in the region of the opening.
